Is AD 2001-03-02 a recurring Airworthiness Directive?

No — AD 2001-03-02 is a one-time directive. Verify it was complied with in the aircraft's records.

Which aircraft does AD 2001-03-02 apply to?

AD 2001-03-02 applies to Pratt & Whitney Canada — models PW306A, PW306B. Serial/part conditions may narrow it to specific aircraft.

Airworthiness Directives; Pratt & Whitney Canada Models PW306A and PW306B Turbofan Engines

What this AD requires

This amendment adopts a new airworthiness directive (AD) that is applicable to Pratt & Whitney Canada (PWC) models PW306A and PW306B turbofan engines. This amendment requires removing compressor rotor 2nd, 3rd, and 4th stage drum assemblies and impellers from service before exceeding new, lower cyclic life limits. This amendment is prompted by the results of test analyses that indicate certain compressor rotor 2nd, 3rd, and 4th stage drum assemblies and impellers do not have full published life. The actions specified in this AD are intended to prevent premature cracking of compressor rotor 2nd, 3rd, and 4th stage drum assemblies and impellers which could result in an uncontained engine failure and damage to the airplane.

Applies only to engines with compressor rotor 2nd, 3rd, and 4th stage drum assembly part numbers 30B4149-01, 30B4539-01, and 30B4725-01, and impellers part numbers 30B4183-01, 30B4494-01, and 30B4564-01, installed.

Whether AD 2001-03-02 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.

How AD compliance is recorded

A valid compliance record (14 CFR 43.9) states:

Method of compliance — The specific action taken (inspected, replaced, modified) and to what revision.

Date — When the work was done.

Aircraft time — Total time in service / tach at compliance — how recurring next-due is computed.

Signature & certificate — The A&P/IA who returned it to service, with certificate number.

Is AD 2001-03-02 complied with on your aircraft?

Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.

Applicability is derived from the FAA directive corpus and is advisory, not a legal airworthiness determination. Compliance is established only from an aircraft’s actual records.
